Patio chair



FIG. 1 is a perspective view of a patio chair;

FIG. 2 is a slightly reduced front elevational view of FIG. 1; and,

FIG. 3 is a slightly reduced side elevational view of FIG. 1.

The dotted line showing of the circular member on the backrest of FIGS. 1 and 2 is for illustrative purposes only and forms no part of the claimed design. 

I claim the ornamental design for a patio chair, as shown and described.
